Reviewing dynamical coupled-channel models

Michael Döring (GWU, co-PI) in collaboration with Johann Haidenbauer (Julich), Maxim Mai (Bern U.), and Toru Sato (Osaka U.) have completed a review commissioned for "Progress in Particle and Nuclear Physics". The manuscript discusses the development and application of a specific class of models for extracting amplitudes and resonance content from a wide range of data across various physical contexts. This is one of the stated aims of the ExoHad: collaboration and contributes to its objectives. In particular, so-called dynamical coupled-channel models have been developed over decades to analyze the light baryon sector from meson and photon-induced reactions. However, there have been extensions to meson physics, three-body physics, and even calculations relevant for lattice QCD and neutrino physics. The review also contains a section on baryon-baryon interactions, pentaquarks, and, finally, heavy exotics.
